Microsoft confirmed that Windows 11 will get all updates currently offered to Windows 10, including Patch Tuesday, optional preview, OOB (out of band), and more. Windows 11 is technically Windows 10 (NT.10) and it will also get Malicious Software Removal Tool updates every month to remove known infections from a computer. Microsoft will still offer Intel microcode updates to mitigate known vulnerabilities or hardware issues in CPU if necessary. Microsoft is planning to offer LTSC version of Windows 11 for those who prefer to use Windows for extended periods, but we don’t know when it will be released.
